I see what you mean.

As pg points out: "One of the things I always tell startups is a principle I learned from Paul Buchheit: it's better to make a few people really happy than to make a lot of people semi-happy." (http://paulgraham.com/13sentences.html)

Regarding the fact that they are all "we are the x of y of z" and seem derivative, pg says:

"One good trick for describing a project concisely is to explain it as a variant of something the audience already knows. It's like Wikipedia, but within an organization. It's like an answering service, but for email. It's eBay for jobs. This form of description is wonderfully efficient. Don't worry that it will make your idea seem "derivative." Some of the best ideas in history began by sticking together two existing ideas no one realized could be combined." (http://ycombinator.com/howtoapply.html)
